WILLIAM J. BREWER, OF BROOKLYN, NEW YORK.

ROLLER-BEARING WHEEL.

To all whom it may concern:

Be it known that I, WILLIAM J BREWER, subject of the King of England,and resident of Brooklyn, in the county of Kings and State of New York,have invented certain new and useful Improvements in Roller- BearingWheels, of which the following is a specification.

The invention relates to improvements in roller-bearing wheels orpulleys arranged for rotation upon a fixed axle or shaft; and the objectof the same is to provide an antifriction roller-bearing of slmpleconstruction, capable of receiving and transmitting normal workingstresses and adapted for operation in conjunction with auxiliarysupporting or bearing surfaces for the moving parts to withstand moreeffectively the increased stresses incidental to shock from temporaryoverloading; and a further object includes certain construction forapplying lubricant to the operating parts.

I11 describing the invention in detail reference is had to theaccompanying drawings, forming part of this specification, and whereinlike characters of reference are used to designate like parts throughoutthe several views, and in which:

Figure 1 is a side view, partially in section, of the improved wheelembodying my invention; Fig. 2, a transverse section through the body ofthe wheel and the rollers; and Fig. 3 is a transverse section showingthe auxiliary bearing members.

The invention as herein shown is applied to a chambered sheave-wheel,having an integral side wall 1 and an oppositelydisposed separable sidewall 2, both provided with interior brace-hubs 3 and secured togetherwith cross-bolts 4, the end members of which are disposed in recesses topreserve a smooth exterior for the wheel. A central shaft or axle 5 isloosely embraced by the side walls of the wheel and also engaged by aseries of rollers 6, mounted within the wheel-chamber for loose rotationupon the spindles 7, the latter being fixed in the side walls of thewheel. Extending through the chamber of the wheel and adjacent therollers and central shaft are a series of transverse bearing-bars 8,integral with the side walls and provided with cross-ties 9 foradditionally securing the side walls together. Recesses or pockets 10for receiving and distributing a lubricant are provided in thebearing-faces of the bearing-bars adjacent Specification of LettersPatent.

Serial No. 505,538.

the rollers and central shaft, these faces being so disposed as tomerely clear such adj acent parts when the wheelis working under anormal load to permit of its free and frictionless rotation.

Upon the application to the wheel of a sudden or abnormal load ofsufficient amount to cause abrasion between the rollers and shaft, thebearing-bars will be e11- gaged by such members and temporarily presentan increased bearing-surface for the transmission of such stress to theshaft, thereby diminishing the direct pressure between the rollers andshaft to increase the durability thereof.

Lubricant may be supplied to the wheelchamber through asuitably-arranged opening (not shown), and by the rotation of the wheelits distribution will be elfected over the several bearing surfaces andoperative parts, the pockets in the bearing-bars serving to increase thedistribution.

l/Vhat I claim as my invention and desire to secure by Letters Patent,is

1. In a roller-bearing wheel, the combination with an axle or shaft, achambered wheel-body mounted thereon, rollers rotatable in the body andengageablewith the shaft, and laterally-extending bearing-bars betweenthe side walls of the body having faces adapted for incidentalengagement with the axle and the periphery of the rollers.

2. In a roller-bearing wheel, the combination with an axle 0r shaft, achambered wheel-body mounted thereon, rollers rota table in the body andengageable with the shaft, and laterally-extending bearing-bars betweenthe side walls of the body having recessed faces adapted for incidentalengagement with the axle and periphery of the rollers.

3. In a roller-bearing wheel, the combination with an axle or shaft, achambered wheel-body mounted thereon and provided with separable sidewalls, oppositely-dis posed abutting brace-hubs formed on the sidewalls, boltconnections extending through said brace-hubs, rollersrotatable in the body and engageable with the shaft, latorally-extendingbearing-bars between the side walls of the body having faces adapted forincidental engagement with the axle and the periphery of the rollers,and cross-ties extending through the bearing-bars and engaging the sidewalls of the wheel.

4. In a roller-bearing wheel the coinbinw tion with an axle or shaft achambered wheel-body mounted thereon and provided I with separable sidewalls, oppositely-dis posed abutting brace-hubs formed on the sidewalls, bolt-connections extending l through said brace-hubs, rollersrotatable in the body and engageable with the shaft, laterally-extending bearing-bars between the side walls of the body havingrecessed faces adapted for incidental engagement with the a axle and theperiphery of the rollers and cross-ties extending through thebearingbars and engaging the side walls of the wheel.
